Energy service providers are continually faced with the challenge to provide their clients reliable power at competitive prices. Equipment failures, lightning strikes, accidents and natural catastrophes result to long service interruptions. For these reasons, the need to monitor and control substations and take necessary accurate and timely precautions has become of paramount importance to the utility operators. In order to prevent possible substation disruption from unexpected failures, a highly reliable, secure, scalable, robust and cost effective communication network that guarantees strict quality of service between the substations and their remote control center is vital. In this respect, substation automation, which is the creation of highly reliable, self healing power systems that swiftly responds to real time events with appropriate actions, has emerged to ensure the maintenance of uninterrupted power services to the end-users.

Substation Automation System (SAS) evolved in the mid-1980’s from the initial proprietary-based SAS installations to the UCA 2.O based SAS installations, to the new generation IEC 61850. The legacy substation automation protocols and architectures typically provided only the basic functionality for power system automation owing to limitation of networking technology available during that period.

The current generation of networking technologies and protocols has veered dramatically from the previous ones making possible design paradigms never been imagined. Protocols like TCP/IP, OSI standard, Ethernet network technology are among those that made new solutions feasible. These were coupled with the development of high speed computers and networking equipment as well as high speed media like fiber optics and twisted copper cables. With Intelligent Electronic Devices (IEDs), which convert the primary substation equipment into network nodes, a new paradigm of engineering the substation network emerged using a configuration language, called SCL (substation configuration language). As the substation network environment has been converted to one in an IT environment, installations of applications like those of security, operating systems updates, and remote access, (even from the internet if needed), were made possible.

National Grid-Saudi Arabia Substation Automation Implementation Paves the Road Toward Smart Grid Application

Written by Gin Quesada for  Abdulaziz A. Sultan, Department Manager, Telecommunication Engineering and Substation Automation Department of National Grid – Saudi Arabia for presentation at International Society for Automation


This article describes how the initiatives of National Grid SA to adopt the IEC 61850 substation automation system (SAS) technology in its transmission grid is paving the way towards the application of Smart Grid. Since the Company implemented SAS in 2009 it has over 200 new HV and EHV substations have been initiated, some of them have already been commissioned and remaining ones in the long term plan are under various phases of implementation. As the IEC-61850-SAS-based substation is a major cluster of the Smart Grid (SG), the Company has taken the necessary initiatives to incorporate functionalities and technologies that align with the SG roadmap of standards, technologies and requirements. With IEC 61850 at the core, supporting technologies like PRP and HSR of the IEC 62439 standard and Ethernet technologies using IP Version 6 that enable the connection of all power system components are explained. Secure NMS based on SNMP Version 3 is described, along with next generation cyber security technologies to fend off Advanced Persistent Threats (APTs). Described, too in this article are subjects pertaining to integration of RTU, SOE, DFR, PQ, and AMR in the SAS-based substations. Future capabilities to integrate PMUs, substation to substation protection, substation to control centers, process bus employing precision time protocol IEEE 1855, are also described. As soon as IEC 61850- Edition 2 is released, plans for its incorporation is ready, as well as making the substation part of infrastructure for data mining, business intelligence and self-healing power system.

Glenn Quesada hurdles the last of the 7 examinations for MCSE

Glenn Quesada passed the last of the 7 examinations that qualifies him to be Microsoft Certifiied System Engineer (MCSE). He took the last examination last March 25, 2009 at the New Horizons Testing Center, at the Al-Khaleej Training Institute along the Dammam – Khobar Road highway. Earlier he was given Microsoft Certified System Administrator last Jan 7, for completing first 5 examinations. All tests including the 2 latest ones were taken over a period of 18 months. It is to be noted that in SEC Eastern Region he is the only Filipino who was able to complete these certifications in recent years. The first MCSE got his certification in 2002 just in time for the approval of his migration to Canada.

Greetings for a Happy Fiesta 2008 and Foundation Day from Pozorrubio Online Team


To Fellow Pozorrubians & Friends,On the occasion of our Town Fiesta 2008 and its 138th Foundation Anniversary, we wish you all Kabaleyans/ Kailians in Pozorrubio and Pozorrubians all over the world a jubilant celebration.On this special event, we would like to take this opportunity to convey our heartfelt gratitude to all of you for the continued patronage you have accorded our very own cyberhome, Pozorrubio Online Portal, through the years.Foremost, we wish to extend our special thanks to our mayors of the previous and present administrations for their endorsements of the Portal. Their support facilitated our mission to reach out to Pozorrubians in the 4 corners of the earth and in the borderless cyberspace.

On this momentous day, we look back with hearty smile and satisfaction to the years you had been interacting with your fellow Kabaleyans and to us through the Portal.

Now, we look ahead with being closer to you, with a new web or portal design aimed to let you participate more freely and actively in its content development. To an extent greater than before, you, yourself, can now determine what would be seen or ‘decorated’ in our cyberhome, with the new paradigm in web design that we have embraced, called Web 2.0.

We invite you to see the new portal design once again, our gift for you for 2008, and invite other fellow Pozorrubians who have never seen it before, to surf, too.

Pozorrubio Online Portal cyber addresses are:   and

You have reasons to be proud of the Portal. When it was first launched in the late ‘90s, our town, Pozorrubio, was only among the few remote towns projected into cyberspace through the Pozorrubio Online website. It was launched when web making was still in the early developing stage in the country. Since then, it had been using industry-class software to process information, with its server in the Kingdom of Saudi Arabia and back-up servers in host companies in US, and now in Canada.

Maintaining its record of always delivering ‘firsts’, Pozorrubio Online Team this time brings you the latest in web design philosophy, Web 2.0, to achieve enhanced interaction among Kabaleyans. We have used  for our main framework, Microsoft’s latest content management solution, Sharepoint facing the web, in a Windows Server 2003 platform – an approach even local vendors of the software themselves haven’t dared to use yet to implement Web 2.0.

To a greater extent you can now decide on what the content of the Portal should be. You, yourself, can now upload documents, photos, links, announcements, news, take part in discussions. And organize information in an easily retrievable fashion. You can upload documents in MS Word, Powerpoint, Excel, pdf, Visio, jpg, gif,  Autocad,, practically all types of documents you use in the home and office, including animation, music, and video clips.
